WATER PUMP.

Application filed September 17, 1921. Serial No. 501,434.

simple and strong construction capable of lifting a large volume of water quickly a short distance,

Another object of the invention is to provide a water pump which may have the operating parts bodily removed from one well and inserted into another with a mini-- mum effort.

A further object, more specifically, is the provision of an impelling member together with its journals which act to hold the impelling member inproper position with out permitting water or sand entering the bearing. m

In the accompanying drawings Figure 1 is a longitudinal vertical section through a pump disclosing one embodiment of the invention.

Figure 2 is a sectional view through Figure 1 approximately on line 2-2.

Figure 3 is a detail fragmentary sectional view through Figure 1 approximately on line 3-3.

Figure e is a detail fragmentary perspective view illustrating the way the impeller blades are connected to their side plates.

-Refe'rring to the accompanying drawings by numerals, 1 indicates what is known as a well which is a boxing formed of concrete, wood or other material and which has a foundation 2 of concrete or other material provided with an opening or vertical bore 3 merging into the water supply pipe In the accompanying drawings, members 1, 2 and 4 are made from concrete but 'desired some of these could be made from wood or other material, as for instance, the boxing or wall 1.

In the present instance, it is aimed to provide a simple construction which will lift a large volume of water in a minimum time for a short distance, as for instance, from four to six feet or possibly a little higher. In many irrigating systems now in use, it is necessary to elevate the water for a few feet only in order to cause the water to flow in the proper canals and over the land as desired. In a system of thiskind the elevation of the water is only for a short distance but it is very desirable to elevate a large volume at a minimum cost- In the present invention, means have been provided which may be arranged at any desired number of points over an irrigating ,system and in connection with this well an impeller7 and associated'parts are used, said impeller and associated parts being constructed so asto be bodily removed at any time and placed in another well whereby the same operating mechanism may be used to elevate water at a number of different points, In order to carry out this idea the device is provided with a bearing member 5 which is provided with a side wall 6 having an inclined or rounded annular shoulder 8, a plurality of spokes or webs 9 and a, central bearing sleeve 10. The shoulder 8 rests'upon similar annular shoulder 11 formed on the stationary bearing 12, which stationary bearing is an annular sleeve having the shoulder 11 provided as shownin Figure 1 and also an annular flange 13 embedded in the concrete of base 2. The sleeve acts as a bearing for the shaft 1 1 and is maintained properly oiled by oil from a suitable reservoir 15, which oil passes through a downward pipe 16 and then through a horizontal pipe 17 to the shaft 14.

From Figure 1, it will be noted that the sleeve 10 has an integral upwardly extending section 18 over which the bearing sleeve 19 fits, said bearing sleeve being part of a casting 20 secured to shaft 14 by a set screw'Ql or other suitable means and secured to the top plate 22 of the impeller 7 by suitable rivets23. The sleeve 19 is provided with an annular flange 24, which flange is cutout at 25 (Fig. 3) so that when it is moved vertically downwardly into the well, it may pass the overhanging shoulder or hook 26 preferably formed integral with one of the spokes or webs 9. After it has been properly positioned it will automatically remain in, place by the'action of gravity and will act as means for connecting the parts together when it isdesired to remove the shaft 14, impeller 7 and associated parts including the member 5.

The impeller 7 is provided with not only a top plate 22 but a bottom plate 22, said bottom plate having a central opening 27 I place by suitable anchoring rivets 29 which opening is Substantially the same size as therbearing member 5.v These plates are connected by impelling bladeSLQS held in 4:). These rivets are provided with enlarged ends 30 fitting in suitable'ope'nings inthe respective blades QS a-nd extendingthrough apertures in the respectiveplates 22 and 22, said ends being riveted or upset. It will-be noted that the bearing member 5 supports the impeller an appreciable distance above the base 2 whereby therewill be no danger of the impeller striking any irregularity of the .base or any foreignmatter accidentallyv deposited thereonL' 1 I I In .case it should be desired to remove the impeller 7 and associated parts including the bearing member 5 and place the same in another well,-.,the shaft l l is merely raised and the impeller will be readily elevated. In case the upper structure isformed. as shown. in'Figure 1, the bolts 31 must be disconnected before the shaft l4; and associated parts may be removed. Ordinarily, however, the bolts 31 and the covering plate 32 are not used.

regard to the covering plate 32, it is to be noted that thisstructure is shown in Figure 'l and is designed to .be used where the pump acts as a force-pump to a limited extent. Where it acts merely as an elevating pump, the covering plate or cap 32- may be omitted, When used as shown in Figure l itiprovides a packing gland 33 to makea substantially water tight structure and is held in place by the bolts 31 which also hold the cross bar 32 in place. Suitable blocks 35 are arranged between bar 34v and plate 32 so as to space the bar a suflicie'nt distance upwardlyto permit the proper action of the any, desired point.

plate 32. The bolt 31-extend's, through an annular crown 36 whichis secured tothe wall ,1 inany desired manner, as for instance, by a filling of cement or concrete 37. The water elevated passes out the discharge pipe 38 to Asshown in Figure 2a large number of bolts 31 are used and the I plate 32 is utilizedi but these bolts are all unthe chamber-42 of well l will be filled parnecessary except two for the bar 34 where the plate 32 is elin'iinated-lf desired, a

suitable thrust bearing 38 maybe used for supporting the. pulley 39, which pulley is rigidly secured to a shaft 14: by any suitable means, as forinstance, a set screw 40. This pulley is driven by a belt ll, which belt is driven by any suitable power. v

The well 1 and associated parts are preferably arranged so thatthe'water in the pipe t will flow under the action of gravity until tiallyL Preferably, the parts are arranged so that the water will be normally as high as the top of theimpeller 7 so that when said impeller is rotated it may lift the water and permit fresh water to be automatically fed in under the action of gravity. Sometimes.

the head of water may'not be as high as de sired and when this occurs, the impeller must draw the water. into the chamber/l2 and then raise the level of water in the chamber until it flows out the pipe 38. The bore 3 and also the part of the pipe t acts as ajlower compartment while chamber 4L2 acts as the upper compartment and the impeller acts as elevating means for.v elevating the water chamber 42 and, consequently, to a certam extent acts as suction means forpdrawing the water from the lower compartment. v

plates and connected thereto, and a tubular bearing guiding member connected to one. of said plates centrally thereof. U p p i v 2.
